Shrinking DB's And Log Shipping
Jan 18, 2002If you shrink a production db on server 1 which is using log shipping to restore to server 2. Does the db on server 2 also shrink?

View 1 RepliesI've been searching and reading for best practices on how to maintain a reasonable log file size while engaging in Log Shipping. I have found plenty of information on these subjects on their own, but not on how best to shrink your log size without breaking your log shipping integrity.
I apprecaite your help.
Hi
I could not able to find Forums in regards to 'Log Shipping' thats why posting this question in here. Appriciate if someone can provide me answers depends on their experience.
Can we switch database recovery model when log shipping is turned on ?
We want to switch from Full Recovery to Bulk Logged Recovery to make sure Bulk Insert operations during the after hours load process will have some performance gain.
Is there any possibility of loosing data ?
Thanks
Hi,
I 'm sure I am missing something obvious, hopefully someone could point it out. After a failover log shipping, I want to fail back to my inital Primary server database; however, my database is marked as loading. How can I mark it as normal?
I did the failover as follow:
I did a failover log shipping from the 2 server Sv1 (Primary) and Sv2 (Secondary) by doing the following
1) Stop the primary database by using sp_change_primary_role (Sv1)
2) Change the 2nd server to primary server by running sp_change_secondary_role (Sv2)
3) Change the monitor role by running sp-change_monitor_role (Sv2)
4) Resolve the log ins - (Sv2)
5) Now I want to fail back - I copy the TRN files to Sv1 - use SQL Ent to restore the database at point in time. The task is done; however, the database is still mark as loading. I could not use sp_dboption.
I appreciate any suggestion.
Thanks in advance
1) Does shrinking a db have any side affects ? Or this is pretty much a normal
operation ?
2) Also in db options, is it recommended to have auto shrink checked ?
Thanks for your help.
I am new to SQL server.
We have many databases for which log files have grown much bigger. The one I need to Shrink immediately has 16 MB .mdf file and 12 GB of .ldf file.
I will very much appreciate, if somebody can help me with step by step process to shrink the database/log file (some way). We are in a crunch situation
Thanks
Hi all,I've deleted a lot of albums but the size of personal.mdf isn't shrinking - how do i go about acheiving this? I've tried to shrink it in sql management express but the file is read only..
please help!
thanks
I have a webhost where it seems my control of my database is fairly restricted. I cannot backup the database because I don't have the necessary permissions. I cannot perform a DBCC SHRINKFILE (permissions) - and many other DBCC commands. I ran into a problem where my log file filled up during the middle of the day and impacted my operations - data was lost.
I found some TSQL for shrinking the log file, but the statement:
SET @TruncLog = 'BACKUP LOG [' + db_name() + '] WITH TRUNCATE_ONLY'; EXEC (@TruncLog)
will not execute because I cannot execute the BACKUP LOG command (permissions)...
Is there anything else I can do, or am I to far up the creek (w/o my paddle)??
Thanx

HiRunning SQL 7 sp3 on NT 4
I have a database that has the auto shrink option turned OFF. However, the log file seems to auto shrink after the user
runs bulk insert.
The log file is not setup to auto grow either.Any ideas.
Thanks,

I have a 13 Gig Log File with only 121 Mgs of space used. I have run the DBCCSHRINKFILE command and it has shrunk it by about 100 Mgs. Why can't I get it to shrink to a reasonable size.
View 2 Replies View RelatedI've been trying to shrink my SQL 7 Transaction log after it had grown to 30+GB's. After running the command dbcc shrinkfile 'filename' and the new size, I'm getting a result set of:
DbId FileId CurrentSize MinimumSize UsedPages EstimatedPages
------ ------ ----------- ----------- ----------- --------------
6 2 640 128 640 128
(1 row(s) affected)
DBCC execution completed. If DBCC printed error messages, contact your system administrator.
However my transaction log remains the same size. Any advise would be appreciated!
I'm having a problem shrinking my transaction log. I have a 1GB database with a 500MB transaction log. The transaction logs are backed up every 10 minutes but it has grown to 2.2GB. I've tried backing the transaction log with TRUNCATE_ONLY and then tried doing a DBCC SHRINKFILE but it doesn't seem to work. I've checked if there were any old, long running queries but there is none. What else can I do to reduce the transaction log size?
I've had a thought to create a secondary log file and then delete the primary but that isn't allowed. Is there anyway I can make the secondary log file the primary and vice-versa? This way I should be able to delete the secondary log file to reclaim space.
Any assistance is appreciated...
Many thanks,
Michelle
Have a 6G data file in a single filegroup.
Using dbcc shrinkfile to shrink.
Does not have any effect.
Any ideas?
We have a database that was created with a 50 MB transaction log, that is set to autogrow. Due to activity the log periodically grows to over 200 MB. So we expanded it to 200 MB. But everytime the log is backed up, it shrinks to it's original size of 50 MB. The autoshrink option is not set, and no one is manually shrinking the log.
Any idea what could be causing this?
We are using SQL 7, SP 3.
Thanks!
Hello all,
I am having a problem truncating a transaction log. The truncate and database shrink commands execute successfully, but do not reduce the size of the transaction log.
Thanks in advance for any help on this issue

Hi, is there any other way to shrink the log file other than truncating every time it gets bigger... I have a 800MGs database and the log is getting as big as 11Gigs... any suggestions other than truncating it? Is there a way to set it off?
View 1 Replies View RelatedI have a 1.2 gig db which has truncate checkpoint set and over 850 meg of free

Hello,
Ran the Andrew Zanevsky script to shrink the Tran log, this works great, but say the log gets shrinked to 30MB, I then expand it to 40MB, then sometime within a 24 hour period it magically gets reset to 30MB. The database is a standalone DB, and is on SQL7 SP1 the script I ran can be found @ http://www.pinnaclepublishing.com/sq/SQMag.nsf/WebIndexByIssue/F36C151BD80FAD8F852568D0007799BE?open.
Can anyone please give some insight into this or maybe a flag that got reset somewhere?
Thanks in advance

Hi again
Damn, people, how to shrink log file. I've tried several times with
DBCC SHRINKDATABASE ( database_name , TRUNCATEONLY)
and
DBCC SHRINKFILE (log_name, final_MB, TRUNCATEONLY)
and the log still is _untouched_
I have got big table, about 190 mln records (15 GB) and after simple update the log is very big but unnessesery.

HI-
I've got a development server where I periodically have to allow the tempdb to grow to over 2GB. However, I'm at a loss on how to shrink the tempdb back down to a manageable size. I need the drive space on the server for other tasks. This seems like such a simple thing but I can't find information anywhere on it.

I have a database that is 9 Gig in size and I am no longer needing the information that was stored in this database.
So I deleted the User tables that I created and deleted the User stored procedures.
I performed the Shrinking database feature and it only shrunk my database to 2 Gig.
How come it did not shrink the database to at least 10 MB since I no longer have data stored in the database?
i havae a database size of 1000mb with used as 507.50 and unused as 492.50. i tried with commands like dbcc shrink file and dbcc shrink database but i could not get the result as what i need. I need to shrink in such a way that it should have 25% of the used space as free space. could any one help
View 4 Replies View RelatedI'm trying to shrink the log file. I have used the suggestions that I have seen posted previously. This is the script I've been using.

Before I ran this the used portion of the log was 1795.12 MB, the free was 1570.50 MB for a total of 3365.62 MB.
After completing this the used portion was 25.62 MB, the free space was 3263.50 for a total of 3289.12 MB. It only srhunk about 26 MB. Why won't it shrink it anymore. There was plenty of data in the used at the time of the shrinkfile command so I would have thought it would have shrunk it a lot more.
Please help. I don't understand why it won't shrink it anymore than it did.
Ideally it seems to me that it would be best to only shrink databases when they
are not in use.
However, it seems this may not be practical, therefore can a Database
be shrunk while it is actively being used?
Thanks !!!
Hi, my log has grown out of proportion after performing an indexdefrag in bulk-logged mode!
Now I cant shrink the damn thing coz I have forgotton how to shrink it when the logical log files are still in use.
Can somebody enlighten me please. thankyou.
error msg: "
Cannot shrink log file 2 (MyDatabase_Log) because all logical log files are in use."

OK here's my dilema:
I have a SQL Server database (in 2000) which is 3 gig in size. I am using bulk-logged as the recovery model (I've tried simple.)
We import 300,000+ records on a monthly basis. This increases the tranlog with each import (and often times records need to be deleted and re-imported due to bad fields on the import files) and it ends up growing the tranlog to over 1 gig by the end of the day.
I've tried and tried but I can't shrink the tranlog! I've used every shrink type command and option (with truncate_only, emptyfile, etc.) but I still can't shrink the tranlog.
The database is set on a once a month backup schedule (which includes backing up the tranlog.)
Any help would be great! I was able to shrink it once after issuing several commands (i.e. dbcc commands + shrinkfile, shrinkdatabase, etc.) but I can't remember the combination of commands I used and I can't get it to shrink last time now no matter what I do!
I cannot use BCP or DTS or any other type of SQL Server importing process! I need to use the Access front end to do the importing (linked tables) because there are simply too many checks it needs to do which BCP or DTS can't handle. I do however use some stored procedures to help with the importing process speed.
Again, Any help would be great as we have 300,000+ records to import today and having a 1 gig tranlog slows things down. How can I shrink a stubborn tranlog which doesn't want to shrink and what's the best type of configuration for this database?
file?
I know how to shrink the log file but I am not sure if I can shrink the MDF file
and how. I am using SQL 2000.
I don;t think my database is that big but the complete backup file is up
to 6G.
this is what is displayed in Taskpad
MDF-------------- 5941M Used 589M Free
Log -------------- 3.58 M Used 12.5M Free
Any suggestion is greatly appreciated.
Thank you
Hi All,
I have steps that I take to shrink transaction log. One of the steps is to delete the transaction log after I detach the database. Am I losing any data by doing that?
how can we shrink the log file to the required size without affecting the live database .....
Thanks in advance
the problem i have is that the tempdb mdf file has been slowly growing over the last couple of months and has filled the disk. i've managed to claim a little bit of space by running dbcc shrinkdatabase but as its a production server would rather not stop and start the service. is there a way of finding out what it taking up all the space and deleting it to reclaim the space?
